The lake is the result of a natural dam that flooded the area. Removal of part of logs and other natural causes of the dam in the 1830s opened access to the Big Cypress Bayou (near modern-day Shreveport, LA) to steamboats for travel and trade along the river. Over the next 40 years, parts of the naturally-occurring log dam kept being removed, slowly draining the backed-up water from the basin. This drainage is why the lake is no longer officially considered “natural.” This also made the lake too shallow for steamboat traffic, which reduced the economic activity in the area.
The search for oil in the early 1900s led to a first in history at Caddo Lake when the first over-water oil well in the U.S. was drilled here. This well attracted other oil drillers, but the area was too shallow and swampy for their large barges. In 1914, a 1,540-foot-long dam was completed across Big Cypress Bayou (near Mooringsport, LA) to make the area more accessible to the drilling barges. This dam created the Caddo Lake of today. Upgrades to the dam were completed between 1968 and 1971 by the Army Corps of Engineers.
President Franklin Roosevelt created the Civilian Conservation Corps in 1933 to provide jobs and job skills to young men (17-25 years old) through work on conservation projects. The workers earned clothes, medical care, food, and a monthly paycheck of $30 for their services. During the second half of 1933, Company 889 of the CCC began building the first structures in what would become the 500-acre Caddo State Park in 1934. Company 857 took over construction from October 1934 through March 1937, converting 15 U.S. Army barracks and a mess hall into log cabins and the recreation hall that can be found there today, among many other structures and infrastructure.Caddo Lake covers over 25,000 acres through east Texas and western Louisiana. It is the most ecologically diverse lake in Texas, housing over 90 species of fish that are proven native to the lake, as well as more than 20 species of mussel. It’s also a thriving ecosystem for the bird and amphibian life in the area. The wide variety of fish species attracts fishermen from all over to come and try their luck. Paddleboats, canoes, and kayaks are all also welcome to venture the 50 miles of paddling trails in the area. The surrounding forest is an attraction for hikers and wildlife watchers, too. In its beginnings, Caddo Lake served its area as a means of trade and transport. Now, after so many decades and getting some cosmetic work, it still serves the area as a tourist attraction and place for enjoying outdoor activities.
